FNQ "winter" wx... false premise.
Strong SE trades bang moist maritime air up against the coastal ranges and it becomes u/s for vfr., low cloud and dzl. caught and killed a few. And one lucky young couple who lobbed into a big tree canopy lived to tell the tale !
Inland OK...depending on the strength of the wind, harder the blow , further in the wx gets...once past COE ...clear as a bell to Broome !
Best times, change of the season..April/ May and post Dry Sept/Oct
